PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Classification of 2-aminobenzenesulphonic acid for effects in the environment
The aquatic toxicity values available for 2-aminobenzenesulphonic acid, indicates no toxic effect on fish and any other tropic levels. Thus, the value which have been considered for further calculation (fish) is LC50 = 100.4 mg/L.
In determining the classification appropriate to 2-aminobenzenesulphonic acid, it is necessary to consider all available evidence concerning its persistence, potential to accumulate and predicted or observed environmental fate and behavior that may present a long-term and/or delayed danger to the structure and/or functioning of aquatic ecosystems. These points are considered below.
Persistence
Available data demonstrates that 2-aminobenzenesulphonic acid is non persistent in nature since it is considered to have rapid biodegradation in the environment. Thus it can be inferred that 2-aminobenzenesulphonic acid is non persistent in character.
2-aminobenzenesulphonic acid is non persistent and so do not satisfy the criteria for classification as persistent (P).
Potential to accumulate
Measured log Kow values for 2-aminobenzenesulphonic acid is less than 4 (Kow = 1). The potential for 2-aminobenzenesulphonic acid to bioaccumulate in the tissues of organisms that inhabit aquatic or terrestrial matrices is negligible as the BCF factor for the substance is less than 1000.
The calculated BCF of 2-aminobenzenesulphonic acid is 3.2 dimensionless and below the threshold of 2000.
2-aminobenzenesulphonic acid does not satisfy the criterion for classification as bioaccumulative (B).
The toxicity values of fish, invertebrates and algae are LC50 = 100.4 mg/L, LC50 = 106.623 mg/L and EC50= 170 mg/L, respectively. The end point result values indicate that the substance will not have any toxic effect as the values are beyond the classifying range. So, the substance will not qualify for aquatic toxicity classification as per the CLP regulation.
So, 2-aminobenzenesulphonic acid does not satisfy the environmental effects criterion for classification as toxic (T).
Thus it can be inferred that 2-aminobenzenesulphonic acid is not a PBT chemical
